F and E Tank Overflowing?

[@stuartlockwood9645]

Hi Al, and Jan, ☺, thanks for another interesting video mate, hope your both keeping well, best wishe's to all, Stuart Uk.

[@dereton33]

Thanks Stuart.

[@JonathanPriceUK]

Thanks

[@dereton33]

Thanks for your kind donation Jonathan.

[@jamiefors5062]

Nice one Al, believe it or not I had this problem, changed the tank, lasted about 10 years and happened again, lets hope this one lasts longer 🤣🤣🤣

[@dereton33]

Fingers crossed Jamie..

[@markennyee]

Hi when you said you changed the tank is that the hot water cylinder of the F & E tank cheers

[@fortune461]

Hi great video, any idea why when i have the heating on that water trickles up through the vent and in to the small header tank? also the pipes in hot press feel warm all the way up to the attic

[@dereton33]

A blockage in the system, try running system cleaner, followed by fresh inhibitor

[@fortune461]

@dereton33 thank you

[@mattridler377]

Thanks for this explanation. I have this problem. Changed the ball valve in the f and e tank and still the same. I’m guessing I could 100% prove it’s the coil by lowering the level in the main tank so it’s below the level in the f and e tank. The pressure should be to low to pass water into the f and e tank via the coil then? Cheers for your help

[@dereton33]

Yes, exactly

[@Ste2023]

Hi al , When you say , pin hole in cylinder..do you mean the Immersion Tank needs replacing..? 😮

[@dereton33]

Yes.

[@Ste2023]

@@dereton33 oh dear 🤔 ££££

[@sergiofernandez3725]

Great explanation. Would the F and E tank not benefit from non-return valve ?

[@dereton33]

No it would have enough pressure pushing back up to prevent it filling.

[@An.Individual]

I had an overflow on the main tank last week. When I went up into the loft the next day, everything was fine, water level normal no running fill valve. Maybe it filled via the vent but I didnt notice anything.

[@dereton33]

Best keep an eye on it.

[@NodrogMacphee]

What does the overflow pipe/vent from the immersion tank do ? Ive recently changed the tank (old zinc one) and wondered why we have an overflow (its never been in operation for over 40 years).

[@dereton33]

It allows for expansion into the roof tank if the water gets to hot.

[@NodrogMacphee]

@@dereton33 That dreaded pin hole or electric heater addon no doubt.

[@barryeverton2532]

I have very hard water, I think, and my mains water is fine and clear, however in my shower after a while I get an orange residue build up. I end up washing it off with a white vinegar spray. Is this also a sign of cross contamination?

[@dereton33]

No. Limescale builds up in the shower head and causes this. Al

[@barryeverton2532]

@@dereton33 Ok thanks. What's the best stuff to clear it then?

[@kwameopokukwarteng]

Could a blockage at the section where the cold feed enters the heating system cause the overflow?

[@dereton33]

Yes and it often does.

[@kwameopokukwarteng]

@@dereton33 thanks. Because the cylinder at the customer's property is relatively new

[@AH-xf7qf]

Hi. Is cross contamination almost a certainty if the issue is a result of a faulty coil? I currently have this issue and hoping to have it fixed tomorrow by replacing the ball valve. Another question - would the hit water show some discolouring if there indeed is cross contaminating in the cylinder? Cheers!

[@dereton33]

Cross contamination is a certainly possible. Renewing the tank valve will not stop it. The cylinder will need replacing.

[@dereton33]

Also depends how bad the contamination is to the amount of discoloured water from the taps

[@AH-xf7qf]

Many thanks for your response. We haven't seen any discolouration when running the hotwater. Just hoping replacing the ball valve will stop the overflow in the F&E. If it doesn't then looks like it will have to be a new cylinder job. Oddly the overflow started the same night our mains in the area wasn't working and after Severn Trent came out 5 hours later to have it fixed. Oddly the dishwasher also stopped draining the same night!? Surely not a coincidence! :(

[@barryeverton2532]

Hi, can a faulty temperature sensor on the tank cause this as well?

[@dereton33]

Yes it could, but you would know if it was that as the hot water would be very hot. Al

[@barryeverton2532]

Well yes it is

[@markennyee]

Hi fantastic vdeo well explained however I have had this problem for 19 months now I have paid plumbers and a gas safety tech to fault find and fix the problem plumbers did nothing heating engineer told me I need a new boiler ?? which even I know is wrong any advice would be gratefully accepted 😁😁👍👍

[@dereton33]

You more than likely need a new cylinder

[@petehiggins33]

While the overflow is running turn off your stop cock, make sure its fully off and isn't allowing any water flow. Wait for ten minutes. If the overflow stops then you need to renew the washer in the ball cock in the F&E tank. If the overflow continues then you *probably* have a pin-hole in your heater coil. Turn on a hot tap until the water in the hot water header tank falls below the level of the overflow in your F&E tank. If the overflow from the F&E tank stops then you *definitely* have a pin hole in your heater coil.

[@markennyee]

@@dereton33 Thank you for replying I totally agree and I'm no plumber or heating engineer so the question is why have they said nothing about the cylinder and told me I need a new boiler ? even if I got a new boiler it wouldn't solve the fault would it ? many thanks

[@markennyee]

@@petehiggins33 ball valve shuts off correctly no leakage turned mains water off and still get the F & E tank over flow leak ?

[@jimfisher5916]

@@markennyee I have this exact same fault and I can also hear a faint ringing in every room as though water is circulating through heating pipes, do you have this sound? Cheers!

[@BobWynn]

If the water mixes does that mean we're bathing in radiator water?

[@dereton33]

Err yes.

[@BobWynn]

@@dereton33 Wouldn't the water look dirty?

[@nixy102]

Can you explain what is F and E? You keep saying this terminology in previous videos as well? F and E??

[@sarge9733]

Feed and expansion

[@dereton33]

Thanks Sarge.

[@--legion]

Chap from British gas didn't fix it, said a powerflush is required. Chap from Homeserve didn't fix it, also said a powerflush is required. Powerflush yesterday... Still dripping.

[@dereton33]

Inner coil of the hot water cylinder leaking.

[@--legion]

Engineer came and said exactly the same thing. So you were spot on.

[@timwhittey4121]

Shame it's not possible to get inside the tank to solder up the hole. Some genius at NASA should have worked out how to fix it via the immersion unit hole by now. My F&E tank has a thick layer of orange scum you could walk on. Wonder where that came from!?

[@dereton33]

The dark side ha ha.

Thanks @dereton33

[@dereton33]

No problem.
